pumpkinkid i have tested this mod a lot as Highway says there is a minor fix that needs applying, if u look here http://www.phpbb.com/community/viewtopi ... 5#p4224145
you can find the fix.
I have installed it 4 times on my local server to be sure it worked everytime, I have tested it thoroughly by adding loads of test users with the reffere filled in and left empty etc.
What I don't understand is why the autocomplete refferer field doesn't work on the live system, i uploaded the files, purged the cache. refreshed the template, refreshed the theme.
I have since run the upgrade on a fresh copy of my live on my local webserver and again the autocomplete works fine?
Could it be a permissions error on the java script file?
